Breaking capacity is rated at 6 kA Icn per EN 60898 and 20 kA Icu per IEC 60947-2. At 20 kA Icu it clears faults without welding the contacts, which is the number a panel designer checks for coordination with the upstream device. Rated insulation voltage is 440 V, overvoltage category III, which covers fixed-installation distribution boards. The IP20/IP40 rating means the breaker body is finger-safe (IP20) and the terminals, when wired, are protected against solid objects over 1 mm (IP40) — standard for enclosed distribution boards. Mounts on DIN rail, 35 mm wide, 88 mm tall, 69 mm deep — fits a standard modular enclosure with one module width per pole. Snap-on DIN rail mount, single-module width per pole (17.5 mm per pole, 35 mm total for the 2-pole). Terminal screws take up to 2.8 Nm tightening torque — the bi-directional cylinder lift terminal accepts solid or stranded copper up to 25 mm². For a panel builder, that torque spec means a standard electric screwdriver set to 2.5 Nm won't strip the terminal; hand-tighten the last quarter turn.","metaTitle":"ABB 2CDS251103R0105 MCB, B-Curve 10A, 2-Pole, 6kA Icn","metaDescription":"ABB S200 series miniature circuit breaker, 10A rated current, B tripping characteristic, 2 poles, 6 kA Icn / 20 kA Icu breaking capacity, DIN rail mount, IP20/IP40.

For a direct B-curve 10 A 2-pole replacement, the 2CDS251103R0105 is the standard offering; no pin-compatible alternative is needed as the S200 family shares the same footprint across ratings."},{"question":"What compliance documentation is available for this breaker?","answer":"The S200 series carries IEC 60898-1 and IEC 60947-2 certification, with CE marking for the European market.
